SMBUS Battery communication.

I am developing for Solo and would like to have a controlled shutdown. 
1: What is the SMBus command to shut down battery ? (make it "switch off" ?) 
2: is there a register I can poll to read out number of battery button presses ? (or starte of the button)  - so that software can respond to a single, or series of clicks, not only the "longpress=off"

Thank you.
